2021-05-03scripts: fix generation update-binfmts templatesSilvano Cirujano Cuesta
This patch fixes the update-binfmts templates being used in the script scripts/qemu-binfmt-conf.sh when the option --debian is used. Fixed issues are: - Typo in flag 'credentials' (previously 'credential'). - Missing flags 'preserve' and 'fix_binary'.

2021-03-13linux-user: manage binfmt-misc preserve-arg[0] flagLaurent Vivier
Add --preserve-argv0 in qemu-binfmt-conf.sh to configure the preserve-argv0 flag. This patch allows to use new flag in AT_FLAGS to detect if preserve-argv0 is configured for this interpreter: argv[0] (the full pathname provided by binfmt-misc) is removed and replaced by argv[1] (the original argv[0] provided by binfmt-misc when 'P'/preserve-arg[0] is set) For instance with this patch and kernel support for AT_FLAGS: $ sudo chroot m68k-chroot sh -c 'echo $0' sh without this patch: $ sudo chroot m68k-chroot sh -c 'echo $0' /usr/bin/sh The new flag is available in kernel (v5.12) since: 2347961b11d4 ("binfmt_misc: pass binfmt_misc flags to the interpreter") This can be tested with something like: # cp ..../qemu-ppc /chroot/powerpc/jessie # qemu-binfmt-conf.sh --qemu-path / --systemd ppc --credential yes \ --persistent no --preserve-argv0 yes # systemctl restart systemd-binfmt.service # cat /proc/sys/fs/binfmt_misc/qemu-ppc enabled interpreter //qemu-ppc flags: POC offset 0 magic 7f454c4601020100000000000000000000020014 mask ffffffffffffff00fffffffffffffffffffeffff # chroot /chroot/powerpc/jessie sh -c 'echo $0' sh # qemu-binfmt-conf.sh --qemu-path / --systemd ppc --credential yes \ --persistent no --preserve-argv0 no # systemctl restart systemd-binfmt.service # cat /proc/sys/fs/binfmt_misc/qemu-ppc enabled interpreter //qemu-ppc flags: OC offset 0 magic 7f454c4601020100000000000000000000020014 mask ffffffffffffff00fffffffffffffffffffeffff # chroot /chroot/powerpc/jessie sh -c 'echo $0' /bin/sh Signed-off-by: Laurent Vivier <laurent@vivier.eu> Message-Id: <20210222105004.1642234-1-laurent@vivier.eu>

qemu-binfmt-conf.sh when it is used with systemd needs to know for which CPU the systemd-binfmt.service file must be created (i.e. "--systemd ppc"). But sometime, for instance for test purpose, we need to create an entry for all known architectures. This patch entroduce the "ALL" parameter for this purpose.

2016-06-07linux-user: Fix qemu-binfmt-conf.sh to store config across rebootLaurent Vivier
Original qemu-binfmt-conf.sh is only able to write configuration into /proc/sys/fs/binfmt_misc, and the configuration is lost on reboot. This script can configure debian and systemd services to restore configuration on reboot. Moreover, it is able to manage binfmt credential and to configure the path of the interpreter. List of supported CPU is: i386 i486 alpha arm sparc32plus ppc ppc64 ppc64le m68k mips mipsel mipsn32 mipsn32el mips64 mips64el sh4 sh4eb s390x aarch64 Usage: qemu-binfmt-conf.sh [--qemu-path PATH][--debian][--systemd CPU] [--help][--credential yes|no][--exportdir PATH] Configure binfmt_misc to use qemu interpreter --help: display this usage --qemu-path: set path to qemu interpreter (/usr/local/bin) --debian: don't write into /proc, instead generate update-binfmts templates --systemd: don't write into /proc, instead generate file for systemd-binfmt.service for the given CPU --exportdir: define where to write configuration files (default: /etc/binfmt.d or /usr/share/binfmts) --credential: if yes, credential an security tokens are calculated according to the binary to interpret To import templates with update-binfmts, use : sudo update-binfmts --importdir /usr/share/binfmts --import qemu-CPU To remove interpreter, use : sudo update-binfmts --package qemu-CPU --remove qemu-CPU /usr/local/bin With systemd, binfmt files are loaded by systemd-binfmt.service The environment variable HOST_ARCH allows to override 'uname' to generate configuration files for a different architecture than the current one.
